A bunch of us F10 M5 guys got to do the M6GC launch at COTA in Austin and once you go CCB it would be very hard to go back after driving them on the track. Great bite and no fade and that was on that heavy car!

The question is are they going to be covered under the maintenance plan? As for me, I would do the CCB.

Yellow Rose of Texas & COTA = Austin Yellow Metallic.

If the CCBs were not and the steel rotors are I think they would have a hard time justifying the up charge for them.

For me I don't think they're worth it given that pads and rotors are covered under the maintenance plan. It may go to the track a few times while I own it and I like the blue calipers better anyway.

If the CCBs are covered under warranty and they are offered for significantly less than they are on the M5 and M6, then I think they're a must even if one doesn't track simply for the significant reduction in unsprung weight. I felt a noticeable gain in weight when I went from 220Ms to 359Ms on my car, and that was around a 2-3 pound per corner difference, not a 7 pound difference like in the CC vs steel brakes.

I can almost guarantee that the CCB's will NOT be covered by maintenance plan. that said, I think I'm going to take the plunge. My plan would be to get steel rotors for them when the CC rotors wear out - that's what a lot of the P-Car guys do when their rotors wear out. I have to imagine the aftermarket will quickly develop a set of steel rotors for them.

also, I don't expect them to be much cheaper than the CCB's on the M5/6, etc. although the rotors are slightly smaller, the M3 looks like it's going to get fixed, 4-piston calipers on the rear. A huge upgrade from the sliding calipers on the M5/6 CCB package.

Do we know anything about the specs on the wheels on the M4?I am talking about offsets as I am curious whether my present track setup will work on a M4 with ceramics.I presently run a 18x10 25p for the track.

Reading from the dealer order guide, it seems CCB requires either option for the 19" wheels, so I am guessing 18" wheels will not fit with CCB.

I am also curious to find out about offset and wheel bolt size. If I am not mistaken, the F3X have bigger wheel bolts than the E9X. So it is likely that our E9X track wheels won't fit the F8X

if you read the wheel specs that are required for my Stoptech 380's they say 19" is the minimum size yet I have no issue with running 18's on my present car.I am hoping the same is true with M4 CCB setup.Still need to know about the offsets of the stock wheels.

Most Porsche people who track pull the rotors off, put them on a shelf, install steel and reinstall when it's time to sell. PCCB's wear as fast as steel on the track, not worth it. I have them on a GT3RS, tracked it once with ceramics and then replaced with steel.

One errant rock chip on ceramics and they're done, drop your wheel on the edge of the rotor, whatever...too fragile for real trackjunkies.

Yeah they're not worth it, especially if they're not covered. That's literally giving up part of your maintenance plan, and paying for that loss. The way most have to drive this car, they may be worth 5% of your time behind the wheel.

I am going with the CCB's as it will be the same money (or there about) as going with an aftermarket BBK.I have clients that have a 996 GT3 with CCB 's on it and they have not had any issues with the discs and they have tracked the car a lot.They have done pads twice on it.Considering that I need to do front rotor rings every 10-12 days I think the CCB's might be the way to go in the long run.The newer Porsche CCB's do not have the problems that the early CCB's did on their cars from what we have seen.Yes you need to handle them carefully compared to a steel disc.
